Low-voltage high performance mixer FM IF system
Table 7. Dynamic characteristics …continued
T_amb = 25 C; V_CC = 3 V; unless specified otherwise. RF frequency = 45 MHz + 14.5 dBV RF input step-up.
IF frequency = 455 kHz; R17 = 2.4 k and R18 = 3.3 k. RF level = 45 dBm; FM modulation = 1 kHz with 8 kHz peak
deviation. Audio output with de-emphasis filter and C-message weighted filter. Test circuit Figure 19. The parameters listed
below are tested using automatic test equipment to assure consistent electrical characteristics. The limits do not represent
the ultimate performance limits of the device. Use of an optimized RF layout will improve many of the listed parameters.
